PENCIL CLIP Filed Oct. 22, less INVENTOR @ms {mark I flmm f TORNEY Patented Oct. 26 1937 UNITED STATES PATENT OFFECE 6 Claims.

This invention relates to attachments for pencils and particularly to an attachment for associating a rubber eraser therewith.

In my present invention I provide improved a means for positioning a rubber eraser upon a pencil in a novel and convenient manner and in such a way that it may be readily and conveniently adjusted or renewed.

Other features and advantages of my improved 10 construction will appear from a study of the following specification and the accompanying drawing wherein:

Fig. l is a perspective view of my invention associated with a pencil.

Fig. 2 is a longitudinal cross-sectional. view through the associated pencil, eraser, and my novel means for supporting the eraser.

Fig. 3 is a transverse cross-sectional view taken on the line III-III of Fig. 2.

20 Fig. 4 is a detailed perspective View of one element of my new device.

Referring to the drawing, II} designates a pencil which, in the present instance, is of the conventional wooden variety, but might be any 25 form of similar writing instrument such as an automatic pencil, a pen, or the like.

My improved eraser holding means, in the form illustrated, comprises a pair of opposed elements indicated generally at II and one of these ele- 30 ments is shown in detailed perspective in Fig. 4. Each element I I preferably comprises an arcuate central portion I2 whose radius is approximately the same as the pencil to which it is to be applied. The arcuate portion I2 terminates at its 35 upper end in a substantially flat, somewhat circular portion I3, provided about its periphery with a series of tooth-like projections I 4 which extend in a direction toward the pencil or other writing implement to which the device is intended 40 to be applied.

The portion I3 is adapted to carry upon its outer face, advertising matter, a monogram, or any other desired indicia.

The arcuate portion I2 terminates downwardly 45 in a portion I5 which is adapted to be employed as a clip for retaining the pencil in the pocket of the person using it. The arcuate portion I2 is provided at one of its lateral edges with a semicircular notch l6 and. at its other lateral edge 50 with a semicircular ear or projection H. In this manner two identical stampings II may be employed in opposed relation to form a substantially tubular assemblage which'is adapted to embrace the upper end of the pencil ID; with the semicircular projection I! of one of the memhers I I resting in the semicircular notch I6 of the other member II, and vice versa. The projections I! and the notches Iii are so proportioned that there is normally some clearance between them when the device is in assembled 5 relation.

A retaining or ring member I8 is provided for cooperation with the body of the pencil for holding the opposed members I I in assembled relation upon the pencil. 10

It will be noted that the eraser holding portions I 3 are of sufiicient size to prevent their passage through the ring member I8. In assemb-ling the device the ring member I8 is applied from the bottom and before insertion of the body of the pencil ID. This is accomplished by placing an eraser I9 between the opposed eraser holding portions I4 with the tooth-like projections I4 bearing against opposite sides of the eraser I9 and then sliding the ring member I8 over both clip portions I5, and over the bumps 29, one of which is struck out upon the tubular portion I2 of each element II and into approximately the position which it occupies in Fig. 1. After the ring member has been positioned about the arcuate portions 12 of the opposed members Ii, the upper end of the pencil I0 is inserted between the members II against the resistance of the resilient pocket clip portions I5 hereinbefore described, with the bumps holding the ring memher i8 in a predetermined position.

It will be noted from an inspection of Fig. 2 that each element II acts as a lever having its fulcrum against the inner periphery of the ring member I8. The force applied against the lower extremities of the clip portions I5 by insertion of the body of the pencil Ill between the two clip portions I5 acts to force the parts of the tubular portions I2 above the ring member l8, and the portions I3, toward each other in pencil and 4.0 eraser gripping relation. A considerable mechanical advantage is obtained by this construction and insures firm gripping of the pencil by the members II against accidental displacement and at the same time forces the tooth-like projections I4 into the rubber eraser I9 to prevent dislodgement thereof excepting by removal of the pencil II] from between the elements II.

For the purpose of more clearly illustrating the relationship of the inner diameter of the ring l8 and the members II with respect to the body of the pencil, the cross sectional View, Fig. 2, is taken across corners of a hexagonal pencil, Whereas'in actual practice and in Figs. 1 and 3 the clip portions [5 bear against flats upon hexagonal pencils.

While a single specific embodiment of the invention has been illustrated and described, it is to be understood that the invention which it exemplifies is not to be limited thereby excepting as defined in the appended claims.

What is claimed is:

1. An attachment for pencils comprising a pair of elongated transversely arcuate members adapted for pivotal connection intermediate their ends with their concave surfaces toward each other and adapted to engage and support an eraser between them adjacent one end of the device and adapted to be associated with a pencil by placing the body of the pencil between said arcuate members, and a surrounding sleeve for maintaining said elements in assembled relation.

2. An attachment for pencils comprising a. pair of elongated clamping members having intermediate portions of arcuate cross section, resilient arm members at one end of each of the clamping members, and portions at the other ends of said members for engaging and supporting a rubber eraser, and an encircling sleeve extending about said intermediate arcuate portions of said clamping members to urge said resilient arm members toward the pencil and resultantly to urge said other ends of said members resiliently toward each other to clasp and engage the body of the pencil and said rubber eraser.

3. An attachment for pencils comprising a pair of opposed elongated members adapted to engage opposite sides of a pencil, means pivotally engaging said members intermediate their ends, means adjacent one end of said members adapted to engage an eraser and support it therebetween, resilient means at the other ends of said members to urge said eraser engaging means toward each other, and a surrounding sleeve for maintaining said members in pivotal engagement.

4. An attachment for pencils comprising a pair of opposed clamping members adapted to engage a pencil and an eraser and hold them in fixed relation to each other, said members being pivotally engageable intermediate their ends, resilient means for urging said members into clamping engagement with said pencil and said eraser through said pivotal engagement, and a surrounding sleeve for maintaining said members in pivotal engagement.

5. An attachment for pencils comprising a pair of opposed elongated members engageable with each other and adapted to be applied to a pencil or the like with said members on opposite sides of said pencil and one end of each member projecting beyond said pencil to form opposed clamping members for supporting an eraser, said members terminating at their other ends in resilient arm portions, and an encircling sleeve about said members for maintaining them in assembled relation.

6. An eraser holding attachment for pencils comprising a pair of elongated arcuate elements pivotally connected intermediate their ends, means for supporting an eraser between said elements adjacent one end of the attachment, and a surrounding sleeve for maintaining said pivotal connection.
